Well, yes you can have spinning tires and wheel hop at the same time. Unfortunately for me, that is exactly what I experience, and the pavement proves it by showing a foot of solid rubber mark, then a 3" gap, then 6" of rubber, 3" gap, etc.

I'm not trying to do smokey burnouts. Just trying to launch the car as hard as I can to get the best 0-60 time. In my other cars, the best acceleration usually came with a small amount of wheel spin.

I don't want to throw money at a lot of heavy duty suspension upgrades, like LCA relocation brackets, new tubular LCA's, new springs, heim ends, etc, when a stock V8 camaro/firebird making more hp and tq than my car, can launch hard and have no wheel hop. The factory setup works for thousands of V8 Fbodies, and it should work for my V6 making considerably less hp and tq.

So experience tells me that there is probably something wrong, worn or broken that is preventing the rear suspension from performing properly. So before spending hundreds on race grade parts, I want to be sure that the parts I have are good, because they should be doing the job.

Regarding the discussion of torque and the affect of gears, think of this: A bolt that requires 90 ft/lbs of torque to unscrew it has a 1 foot long box end wrench on it with a 10 lb weight attached to the end of the wrench. That is 10 ft/lbs of torque and will not unscrew the bolt. Hang 100 lbs on the box wrench, and the bolt will unscrew. But if you put a 10 foot extension on the box wrench, and hang the 10 lb weight on it, it will also unscrew the bolt.

Why? Its still just the same 10 lbs pulling on the bolt. So why did 10 lbs break the bolt free on a 10 foot long wrench, but not a 1 foot long wrench?

Because of leverage. The extension multiplies the torque x 10, creating 100 ft/lbs of torque from the same 10 lb weight.

Gears do the same they multiply the available torque. Same as the trans does, etc.

But even with the approx. 20% increase in gear ratio, I think the stock parts should handle the job.

Thanks for all your responses. You have made some great points that have made me rethink a few things. And that's what these forums are all about, no?

Have you owned other 4th gen f-bodies? Everyone I have owned wheel hopped until I started to do suspension mods! I have owned 2 V6 models and 2 V8 models and they all do pretty much the same for me with the stock suspension and a 3.73 or lower gear! The 3rd gens stock suspension was alot better then the 4th gens but they also made less power. I didnt get any wheel hop from my 4 3rd gens I have owned.


You said you didnt have this problem before the new rear. Maybe its the New rear end? Maybe its not setup correctly, or the Eaton posi works different then a stock F-body LSD? Who knows! All that everyone knows is just like how the stock 10 bolts are crap and should be changed out for a stronger rear end that the stock suspension componants are crap that if you want to run your car you need to change them out also!!
